We offer customers rotary union for coolant, and rotary union for coolant applications. These feature housing with straight through or 90° entry for high pressure based applications. Further, these are made available with hard alloy vs carbon graphite sealing faces as well as with Tungsten Carbide and Ceramic Seals.
Frequently Asked Questions
A rotary union is a mechanical device that allows the transfer of fluid (coolant, in this case) from a stationary source to a rotating machine component. It ensures a reliable and sealed passage for coolant in CNC machines, spindles, or other rotating systems.
It allows efficient cooling and lubrication of moving components by ensuring the coolant reaches areas like high-speed spindles or rotating drill heads without leaks or interruptions.
A rotary union (or swivel joint) is a device used to transfer fluid under pressure or vacuum from a stationary inlet to a rotating outlet, preserving and isolating the fluid connection.
Our standard operating temperature for our Rotary Union is -40°F to about 220°F. Some of the components in our Rotary Unions can handle higher temperatures than others.
Rotary couplers transfer fluid, air, or signals between stationary and rotating parts using seals and bearings, enabling continuous flow without leaks during rotation.
